Immigration is a major challenge and opportunity for rich Western countries. Integration of immigrants is a two-way process, the success of which depends both on immigrants and on natives. We provide new evidence on the determinants of individual attitudes towards immigration, using data from...

We study the role of self-interest and social preferences in referenda. Our analysis is based on collective purchasing decisions of university students on deep-discount flat-rate tickets for public transportation and culture. Individual usage data allows quantifying monetary benefits associated...

About 1.4 million refugees and irregular migrants arrived in Europe in 2015 and 2016. We model how refugees and irregular migrants are self-selected. Using unique datasets from the International Organization for Migration and Gallup World Polls, we provide the first large-scale evidence on...

We use a unique survey of Danes who have emigrated between 1987 and 2002 to study intra-family decision-making on international migration. Our survey reached 582 respondents with a Danish partner who was the same as before emigration. We model family decision-making in a bargaining framework and...

We present theory on international migration of dual-earner couples, and test it using Danish register data. Our model predicts that the probability that a couple emigrates is increasing in the earnings of the primary earner. The effect of the earnings of the secondary earner may go either way....
